* This inventionrelatesto stationery and the general object of the invention is to provide a pencilsharpener that will sharpen a pencil by merely pulling the same with a single stroke through the sharpener, withthe result ina persons pocketyor if desired may be a pencil may besharpened ingan' easy and expeditious manner. with very little effort.

A further object of the invention is to providea pencil sharpenerof a size and shape whereby it can be conveniently carried about fixed to a suitable supporting means.

Another object of th'e invention is to pro- 7 wide a pencil sharpener that cuts longitudinally of the pencil and forms a square corner cut, and due tothe novel cutting action thereof, the point formed on the pencil will not be broken as often happens when use is made of a rotary cutter or a stationary cutter making a I rotary out.

A still further object of the invention is to provide a pencil sharpener that includes no rotating parts, no parts to be oiled, is simple in construction, inexpensive to'manufacture,

and efficient in operation and service.

This invention also consists in certain other features of construction and; in the com bination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, ref erence will be had to the accompanying draw- -ings wherein like characters denote like or Figure 6 is a sectional viewtaken approxi mately on line 66 of Figure 4'.

Referring to the drawings in detail, the reference numeral 1' indicates the base plate for the sharpener which forms the subject matter of the present invention and this base plate may be provided with openings to accommodate screws or like securing means for-fixing the sharpener to a suitable supporting member. Rising fromthe'base plate and disposed inspaced parallelism with respect to each other are upright plates 2 which not shape bore 6 to accommodate pencils which are not only hexagon shape in cross section but is of a size to accommodate any shape pencil. p V Y The body has its upper and lower walls formed v-shaped in cross section and the inner portions of these walls are cut away at an inclination so as to be disposed. in converging relation as best shown in Figure 5 ofthe drawings.

Disposed between the uprights intermediate the ends thereof and alsoat the'top's of the upper portions thereof are the top and bottom walls 7 and 8 which together with in cross section and extend in convergingre- Fries lation with respect to each other so as to follow the inclination of the upper portions of the uprights as well as respective upper and lower edges of the projections 3.

The body has its upper and lower walls spaced a considerable distance from the top and bottom walls of the housing for the purpose of allowing a sufficient space to provide for the application and removal of cutting blades 9 and 10, each of which is provided with a shank 11 disposed at an angle to the blade proper and these shanks are apertured for the purpose of receiving screw bolts 12 for securing the blades in cooperative position to the body 5 as best shown in Figure 4c of the drawings. The blades are formed from resilient material and have their free ends terminating in beveled cutting edges 13 which are normally disposed in contacting engagement but are separated when a pencil is passed through the bore 6 as shown in Figure 5 of the drawings. The strip 4 is adapted to limit the movement of the pencil in the sharpener, and when the pencil is withdrawn, it will be obvious that the cutting edges 13 will cut through the wood and lead of the pencil and provide a sharpened end as illustrated in Figures 9 and 10 of the drawings. The square cornered cut produced by the blades is caused by the novel shape of the cutting edges which are disposed in V-shaped formation with the cutting edges of each blade arranged at an inclination as best shown in Figure 8. A shaving receptacle is detachably received by the projections 3 and as shown is provided with a substantially spherical shape body 14 having flanges 15 arranged thereon for frictionally engaging the side walls of the projections 3 as well as the top and bottom walls 7 and 8. The shaving receptacle may be formed from rubber or other like flexible material, so as frictional engagement with the respective parts of the sharpener will be assured.

From the above description and disclosure of the drawings it will be obvious that a pencil may be shapened by the sharpener shown and described by merely inserting a pencil therein until the end engages the strip at, and a single pulling stroke will provide a sharpened end, with the result a pencil may be sharpened in an efficient manner with very little etiort.

Vhile I have shown a sharpener adapted to be secured to a supporting means, itwill be apparent that the base plate 1 as well as the lower portion of the uprights 2 may be dispensed with so as to reduce the size of the sharpener whereby it may be conveniently carried in a persons pocket, hand bag or the like.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I- desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

WVhat I claim is:

In a pencil sharpener, a base plate, a pair of spaced parallel uprights extending therefrom, top and bottom walls formed with said uprights to provide a housing, projections extending in parallelism from the upper portions of the uprights, a strip secured to the free ends of said projections and providing a pencil stop, a body formed in said housing and being spaced from the top and bottom walls thereof, said body being provided with a centrally disposed bore for receiving a pencil therethrough, resilient cutting blades having V-shaped portions merging into straight portions, a shank formed with the straight portion of each blade and being secured to the body in a manner for disposing the cutting blades in converging relation with respect to each other and in alignment with the bore, and converging cutting edges formed with each blade and the edges of said blades being normally arranged in contacting engagement.

In testimony whereof I aflix my si nature.
